Grape plant named ‘Stargrape 2’

ABSTRACT

A new table grape plant named ‘Stargrape 2’, notable for its improved berry color, larger size and cylindrical shape.

Latin name: Vitis vinifera L.

Variety denomination: ‘Stargrape 2’.

BACKGROUND OF THE VARIETY

‘Stargrape 2’ is a new and distinct variety of table grape plant (Vitisvinifera L.) of unknown parentage. ‘Stargrape 2’, which originated as anopen cross, was first selected at Clanwilliam, South Africa in 2003, andwas subsequently asexually reproduced by grafting in 2005 and fruitedthrough successive generations at the same location. ‘Stargrape 2’ hasbeen observed to remain true to type over successive asexuallypropagated generations.

BRIEF DESCRIPTION OF THE VARIETY

‘Stargrape 2’ was first selected for its excellent color and berry size.It is distinguished from ‘Flame Seedless’ (not patented) by its improvedberry color, larger size and cylindrical shape.

The following table shows a comparison of ‘Stargrape 2’ to similarvarieties ‘Stargrape 1’ and ‘Flame Seedless’:

DETAILED BOTANICAL DESCRIPTION OF THE VARIETY

The following-detailed botanical description is based on observationsmade during the 2011/2012 and 2013/2014 growing seasons at Clanwilliamand Wellington, South Africa (USDA Hardiness Zone 10) of 3- to 5-yearold vines planted in a commercial vineyard in 2008 on ‘Ramsey’ rootstock(not known to be patented). It should be understood that thecharacteristics described will vary somewhat depending upon culturalpractices and climatic conditions, and will vary with location andseason. Quantified measurements are expressed as an average ofmeasurements taken from a number of individual plants of the newvariety. The measurements of any individual plant or any group of plantsof the new variety may vary from the stated average. Color descriptionsare made with reference to The Royal Horticultural Society Colour Chart(5^(th) Edition).
